Standard mufflers can restrict airflow, which makes the system less effective at removing radon. Our wide-profile design is engineered to avoid this. It allows you to cut exhaust noise by up to 75% without compromising the suction needed to reduce radon in your home.

Key Features

• Reduce Noise: Specifically designed to target noise at the discharge point by up to 75%.

• High Efficiency: Wide-body design provides virtually no effect on airflow.

• Durable Build: Constructed from heavy-duty Schedule 40 PVC for long-term durability.

• Shipping: Free shipping to the continental U.S. is included in the price.

⚠️ Note on Noise: This product is designed to silence exhaust air noise. It is not intended to reduce mechanical fan motor hum or pipe vibration.

Installation & Compatibility

• Placement: Install the muffler directly above your radon fan for optimal results.

• Pipe Fit: Designed for 4-inch Schedule 40 PVC (Inside Diameter: 4″; Outside Diameter: 4.5″).

• Adapters: Depending on your specific setup, additional reducers or adapters may be required for a seamless fit.

A Note on Appearance: Our mufflers are made from Schedule 40 PVC. Because of the specialized molding and grinding process, units may arrive with minor surface scuffs or marks. These are purely cosmetic and do not affect the performance or integrity of the muffler.
